A trench drain assembly including a flow channel and a frame for supporting the channel in a trench. Sidewalls of the frame have a gradually increasing height between ends of the frame so that the frame creates a gradual slope for the assembly to properly drain. In addition, sidewalls of the frame include spaced lugs that extend outwardly and sidewalls of the channel include spaced lugs that extend inwardly to create an interference fit with the lugs of the frame so that the channel can be easily attached to the frame. During assembly, the frame is lowered onto the channel so that the lugs of the frame are received between the lugs of the channels and the frame is then slid with respect to the channel until the lugs of the frame are positioned below the lugs of the channel to secure the frame to the channel.
